The invention belongs to the technical field of new energy grid connection, and particularly relates to a photovoltaic maximum admission capacity calculation method, which comprises the following steps of: establishing a target function by taking the maximum total capacity of photovoltaic accessed to a power distribution network as a target based on the capacity of each photovoltaic and the numberof the photovoltaic; establishing a first constraint equation based on the active power and the reactive power flowing through each node, the photovoltaic active output and the load power corresponding to each node, the load reactive power and the voltage value of each node, and the line resistance and the reactance value between the nodes; and based on the first constraint equation, solving thetarget function, and taking the sum of the photovoltaic capacities obtained by calculation as the photovoltaic maximum admission capacity. Based on the method, the maximum admission capacity of the distributed photovoltaic access power distribution network can be accurately solved and calculated.
Description
technical field [0001] The invention belongs to the technical field of new energy grid connection, and in particular relates to a method, device, terminal and storage medium for calculating the maximum admittance capacity of photovoltaics. Background technique [0002] In recent years, my country's energy structure has gradually transformed to green and low-carbon, and distributed photovoltaic power generation has developed rapidly. Photovoltaic output has the characteristics of randomness, intermittency, and volatility. With the continuous increase in the proportion of distributed photovoltaic access in distribution networks, distributed photovoltaics have had an important impact on power quality, power flow direction, and voltage fluctuations. One of the main reasons for distributed photovoltaic abandonment is a series of problems caused by excessive access capacity. [0003] However, the national standard "Technical Regulations for Connecting Distributed Power to the Pow...
